Answer 2

Step-by-step explanation:

Question:

A field is 225 m long and 175 m wide. It has two roads in its centre of uniform width of 5 m, one parallel to its length and the other parallel to its breadth. Find the cost of levelling the roads at Rs.3 per square metre.

To find:

the cost of levelling the roads at Rs.3 per square metre.

Solution:

Analyse the problem

We see that total road to be levelled = horizontal road+vertical road-the common portion to both

Area of horizontal road = 225m×5m = 1125 m²

Area of vertical road = 175m×5m = 875m²

Area of common portion: 5m×5m = 25m²

Thus total area: (1125+875-25)m² = 1975m²

Rate : Rs.3 per m²

So, total cost = 1975m² × Rs.3 per m²

=> Rs.5935 Ans.

Hope it's help you in other ways.
